This iconic Cape Breton song is sung by Raylene Rankin of Mabou. The "happy island" is Margaree Island and the composer of the song was Angus Y. MacLellan. Mr. MacLellan, Gaelic scholar and bard, was born at Southwest Margaree in 1878. Most of his poetry was written during the period 1912-1946 when he operated the Margaree Island Lighthouse. His nature poems are considered among the finest in any language. He was patronymically known as Aonghas Iain 'ic Iain 'ic Chaluim. His grandfather came from Morar, Scotland.

This version of An Innis Àigh was recorded in East Margaree for use in the Cape Breton film, Song of Seasons, when Raylene was only 15 years old.
